A few weeks back, our post about borrowing a grill sparked a discussion about whether it's more green to grill with gas or charcoal. The Portland Tribune recently ran a story answering that very question...
They evaluated six categories in what seems to us to be a very subjective and non-scientific test... but what can you expect from a free newspaper? Gas got the nod in air pollution; charcoal in flavor. Charcoal scored another point in equipment cost, gas in fuel cost. The two were even in safety, and the easy on-off of gas got the nod for efficiency.
If you're not in the mood for addition, you can click over to the Portland Tribune for the verdict.
A third choice, pointed out in the comments at the above site, is natural gas. And we should also mention that the greenest choice is not grilling at all. (Clearly, that's not stopped us yet.) Another green way to grill with whatever you already have in the backyard: reduce the amount of meat you're throwing on the grill. You can grill all kinds of vegetables, even swiss chard, with a grill basket that costing about as much as a good steak. Our favorite grilled vegetable is endive, drizzled with a bit of olive oil, of course.
